RE: How to change the default value of Direct Transfer in Transfer Order
Thank you for posting your question about the Direct Transfer on a Transfer Order.
There is no out of the box setting to have Direct Transfer = YES on a Transfer Order as far as I'm aware. You would want your Partner to add that as an Extension/Add-on/Modification.
If you have warehouse functionality however on some of your locations, you will want to be careful. For example, if you have Require Warehouse Receipt, then a Warehouse Receipt Document should be created and the receipt should then be posted from the Warehouse Receipt Document, not from the Transfer Order....so it can get a bit tricky in those scenarios.
Best may be to have have the extension/modification default it from the Transfer Routes, so it can pull from there if you transfer from a vanilla (no warehouse functionality) location to a vanilla location.
Hope that helps:)
